epub to PDF?
Calibre is a great program! I love it. I have used it to convert books into Mobi format to read on my iPhone's Kindle app. However, now I want to convert some epub books to pdf format to read on my Sony PSP using Bookr. If I download a pdf file from the internet, it works fine. If I convert epub to pdf using calibre I can't read it on my computer or on my PSP. It shows as an empty file (0kb).

I am using Ubuntu 10.04, not Windows. Is there a dependency I might need to make this conversion work? Or is there something else I am missing?

I see tons of stuff about converting pdf to epub, I need to go the other way around so none of that is helping me.

Are there any errors?

Try running:

Code:
$ ebook-convert in.epub out.pdf
in a terminal and see if it produces any errors. Also see if it is really producing a 0kb file.

Thanks for the tip. Here is the output of that command. I have no idea how to fix these errors.

The result is 0. Here is a screenshot of the file browser in the GUI which confirms that result:

How did you install calibre? Did you install it though Ubuntu's software repository? I'm thinking you did and the Ubuntu packagers have a bad habit of breaking calibre (as well as other apps) by never testing or using any help they've been offered from upstream. Almost every Ubuntu version has shipped with calibre broken...

pyPDF is used and the bundled version that has some changes to upstream is not being used in your conversion. Install using the binary installer from http://calibre-ebook.com and you will be fine.

I installed it from Ubunut's Synaptic Package Manager. Using the binary installer from your link worked. I successfully converted one book already so I should be able to convert the rest.

Thank you for your assistance.
